Easy to fit, brightly coloured and warm. I use it all the time in the colder months and we've been rained on a few times and my mare has stayed dry. I use them for walking the dogs, riding (hacking and schooling) polish them up and wear to the pub, treking across muddy fields to get horses in, wading into the river to rescue my over-adventurous JRT.... I know some people hate them, but they are the best (and most useful) horsey item I currently own! 
Is it wrong of me to like the leopard print one
Not sure I'd ever live it down if I put her in one of those, my yard is fairly conservative!
enfys & muddy_grey, I was a lucky girl too and got a hosepipe from my OH last Christmas, you're not the only romantic ones! And I got a head torch the year before (although it is very handy having both hands to do the gates in the dark)
Our menfolk are obviously killing two birds with one stone, they'd probably have to buy these items anyway, so they may as well tie a ribbon around it and be done with it! I got a head torch too, it's never been on my head - I put it around senior GSD's neck last thing at night so I can see where he is and can call him back before he goes rousting skunks. 
It was indeed wrapped, very nicely too, as were the mudguards I also received last Christmas (for my bike, not the horse).
Ooo I have a list!
My thermal chaps - bliss in the winter
My gloves with little heaters inside them - like having an electric blanket round your hands!
Vented hat - no hot heads
Mains electric unit that does 42km of fence and goes to 7000v!!!
Pessoa
Head torch
And the neddies
And a house with land
And my other half who is building me stables
ooh, where'd you get the gloves?- and wanna swap husbands?
They also do ones with a little thing you can blow in to warm your hands up that are cheaper... He's just put 9 paddocks worth of fixed posts in for my electric fencing and is now talking stables
